Application filed January 2, 1904. Serial No. 187,448.

' To all whom it may concern:

Be it known that I, EDWIN J. CooHRAN, a citizen of the United States of America, and a resident of Sterling, in the county of White side and State of Illinois, have invented certain new and useful Improvements in Chimney-Caps, of which the following is a specificatlon.

The present invention has for its object to provide a simple and eflicient construction of parts involving a ready and substantial attachment of the chimney-cap to chimneys of different sizes, all as will hereinafter more fully appear and be more particularly pointed out in the claims.

In the accompanying drawings, illustrative of the present invention, Figure 1 is a central longitudinal sectional view at line as w, Figs. 3 and 4, of a chimney-cap embodying the present invention. Fig. 2 is a longitudinal sectional view at line m m, Figs. 3 and 4, of the chimney-cap. Fig. 3 is a top plan view of said chimney-cap. Fig. 4 is a bottom plan view of the same.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the stationary base of the chimney-cap formed in one piece and consisting of a main dome-shape portion having a vertical annular reduced rim 2 at top and a flat outwardly-projecting horizontal web or flange 3, having a depending flange 3 and a horizontal flange 3 at bottom. 1

17 represents pairs of adjustable overlapa shallow recess provided by the construction of the horizontal web 3 of the base of the chimney-cap and secured in such a manner as to permit the horizontal members of each pair of anchor-bars to slide one on the other by means of elongated longitudinal parallel slots 18 in said bars, elongated transverse slots 19 in said web 3, extending in a direction at right angles to the slots 19, and by confiningbolts 20, extending through the series of slots, as illustrated in Figs. 2, 3, and 4.

21 represents vertically-depending prongs on the opposite ends of the respective bars 17, which are adapted for insertion in the chimney-opening, and by the adjustment of said bars which overlap be made to engage against the inner vertical faces of the chimney-opening regardless of the size of such opening,

adjusted affords a substantial attachment of the chimney-cap in place.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. A base for a chimney-cap comprising a dome-shape portion having a vertical annular reduced rim at the top, a flat outwardlyprojecting horizontal web at the bottom, having a depending flange surrounding the horizontal web and a horizontal flange surrounding the depending flange forming a recess or elevated space in the unnder side of the base,

and adjustable fastening means located in said recess or elevated space.

2. A base for a chimney-cap comprising a flat outwardly projecting horizontal web having parallel paired slots located at opposite sides of the base, adjustable overlapping anchor-bars located in parallel pairs beneath the horizontal web and extending across the parallel paired slots, and provided with depending prongs at the outer ends of the anchor-bars, bolts extending through the parallel paired slots, and nuts for supporting the anchor-bars against the horizontal web in their adjusted position either transversely or longitudinally of the base.

3. A base for a chimney-cap comprising a flat outwardly projecting horizontal web having parallel paired slots located at opposite sides of the base, adjustable, overlapping anchor-bars located in parallel pairs beneath the horizontal web and having coinciding slots extending across the parallel paired slots, and provided with depending prongs at the outer ends of the anchor-bars, bolts extending through the parallel paired slots and through the coinciding slots, and nuts for supporting the anchor-bars upon the bolts and against the horizontal web in their adjusted position either transversely or longitudinally of the base.

4. A base for a chimney-cap comprising a flat outwardly projecting horizontal web having parallel paired slots located at opposite sides of the base, and a depending flange surrounding the horizontal web, and a horizontal flange surrounding the depending flange forming a recess or elevated space in the under side of the base, adjustable overlapping parallel anchor-bars located in pairs within the recess, or elevated space, and extending across the parallel paired slots, and

within prescribed limits, however, and as so l provided with depending prongs at the outer pairs within the shallow recess or elevated ends of the anchor-bars, bolts extending 1 through the arallel paired slots and nuts for supporting t e anchor-bars against the horizontal Web in their adjusted position either transversely or longitudinally of the base.

5. A base for a chimney-cap comprising a flat outwardly projecting horizontal Web having parallel paired'islots located at oppo site sides of the base, and a depending flange i surrounding the horizontal Web, and a horizontal flange surrounding the depending flange forming a shallow recess or elevated space in the under side of the base, adjustable overlapping parallel anchor-bars located space, and having coinciding slotsextending across the parallel paired slots, and provided with depending prongs at the outer ends of the anchor-bars, bolts extending through the parallel paired slots and through the coinciding slots, and nuts for supporting the anchor bars upon the bolts and against the horizontal web in their adjusted position either-transversely or longitudinally of the base.
